“…Myelolipomas have been reported in the spleen, adrenal gland and/or liver of wild cats, small monkeys, dogs and man (Ikeda & Downey, 1972;Noble et al, 1982;Zimmer & Stair, 1983;Narama et al, 1985). Some authors considered that myelolipomas are not true tumours, but transformation of mesenchymal cells caused by chronic anaemia (Selye & Stone, 1950;Bingham et al, 1976), because the common sites of this tumour (the spleen, liver and adrenal) are potent haematopoietic organs, especially in foetal life (Narama et al, 1985).…”
